This invention relates to inishing Welts intended particularly `for the upholstery of automobile bodies but useful Wherever it is desired to employ a nishing Welt or similar strip attached by concealed astenings.

In one aspect my invention consists in iin-v provements in nishing Welts oit the type den scribed in U. S. Letters Patent No. 1,226,600. In another aspect, my invention consists broadly in a new article of manufacture, viz., an integrally-fabricated textile or integrally'- Woven finishing Welt. Considering my 1nvention irst as being in the nature of an improvement upon such inishing welts as those shown in U. S. Letters Patent above identified and Which are fabricated from leather, cloth or other sheet material which must be cut, folded, cemented andstitched, and which thus oHer an .opportunity 'or deterionation in respect to their cemented or stitched joints; the Welt of my invention provides a continuous integral structure inherently uniform in its dimensions, superior in strength and Wearing qualities and not subject to deterioration in the respects noted..

Considering next my invention as being a new article of manu-facture comprising an integrally-fabricated finishin Welt, numerous important and valuable eatures Will be A apparent. In the rst place, a Welt so con'- structed offers an inviting opportunity for ornamental finish in that by appropriately varying the character of the Warp and weft threads or the pattern of the weave any selected design lnay be produced in the fabric of the Welt. For example, it is contemplated that a series of silk, rayon or worsted threads may be employed to create a decorative etect along the borders or other partso't the 40 welt. Opportunity is also aii'orded for eniploying a heavier or less expensive warp thread in the backing of the Welt than in the exposed portion thereof and ,this is advantageous both from the standpoint of economy and in that by this expedient a heavy backing may be provided, anording lirm anchorage :tor the attaching nails without impair-ing the oriamentai appearance of the face et the We t. In the embodiment of the invention in shown, the Welt is formed with a plurality of spaced bead v'cores Which are encased in woven tubes and these tubes are merged into an integrally-woven yintermediate'` connecting portion. It will be apparent that such a welt may be produced to good advantage in a loom where the bead cores may be constituted as AWarp ends, and as the sheath's or tubes are Woven continuously upon the bead cores they conform and fit perfectly thereon, incorporating the' cores into the integral structure ot the Welt; Y My invention contemplates a `Welt having cores Woven into its structure and as a 'further preferredfeature, the welt ojf my invention includes an outwardly-extending flange portion Which-isvintegrally Woven with the core-encasing tubes. The fiange portion may be of single or multiple ply and is integral 'with the backing .por-tion.

These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof, selected for purposes of i1- lustration and shown in the accompanying drawings, in which Fig. l is a view in cross section of the Welt, on an enlarged scale; A

Fig-2 is a fragmentary longitudinal sectional vievv on the line 2-'2 of Fig. 1; and- Fig. 3 is a view in perspective ofthe Welt in substantially its normal size.

AvReferring rst to Fig. 3, it will be seen that the Welt selected 'for illustrating my invention comprises a pair of bead cores 17, each of which is encased in a Woven tube 18. Each or the tubes 18 is merged 'intoan outwardlyextending iange portion 22-and these in turn are merged int-o a backing- 24, integrally woven with the iange portions and underlying the same. The welt may be provided with an ornamental stripe 25 at each side of the bead formed by a series of rayon 'Warp threads as will presently be described, and other variations in the materials or Weave may be assorted to einbellish the appearance of the article. The Welt is so Woven that the beads normally contact with each other and cover the backing 24. In attaching the Welt, the beads are temporarily spread apart and tacite 28 may 'then be driven through the baching in the manner as illustrated in Fig. 3. When the beads are released, they close together, concealing and protecting the heads of the attaching tacks.

Referring now to Figs. 1 and 2, it should be explained that the warp threads are represented in cross section in Fi 1 and the weft threads` in cross section in ig. 2. The bead cores 17 are also constituted as warp ends.

l As herein shown, they are represented as composed of a twisted paper cord, although it is to be understood that any desired material may be employed as best adapted for the particular purpose intended for the welt.. For example, a textile cord of twisted, braided or plain strands, a leather, fabric or rubber cord or a wire may be employed.

The warp threads 10 of the sheath or tube 18 are distributed about the periphery of the cores 17 and extend in overlying relationship outwardly from both tubes. The Warp threads 12 of the backing portion 24 extend from one margin or selvage of the welt strip to the other. The weft threads 16 extend laterally of the backing and are interwoven with the warp threads 12 in any suitable order or weave. The weft is a continuous thread interlacing successively with the warp threads of the backing, the plies of the flanges and the sheaths encasing the cores in a manner similar to the illustration in Fig. 1, thereby forming an integrally formed textile. It will thus be seen that each tube 18 is interwoven with an outwardly-extending flange portion 22 having two-or more plies and that the plies of the flange portion are interwoven with a backing portion 24 which connects the two sides of the welt. In other words, the concatenation of the threads is such as to .provide that the sheatlis or tubes 18 for the beads are integral with the backing 24 and side strips or flanges 22. The warp threads 12 of the backing may be of heavier and less expensive material than the warp threads 10 of the tubes 18 and flange portions 22 of the welt. To indicate such difference in character, the warp threads 12 are shown in heavier sections than the warp threads 10;

In the illustrated construction, the flange portions 22 of the welt are u nited to the backing 24 by spaced warp binder threads 14 which, as shown in Fig. 2, are arranged to intermesh with the weft threads 16 in both the backing and in the iange portions. The warp binder threads are shown as spaced from-each other by a yseries offour warp threads, although the number and arrange `ment of the warp binderthreads is of secondary importance and may be selected as desired. In the illustratedwelt the four warp v threads 13 located between the warp binder threads 14 in the upper ply of the ange portion are preferably of silk orrayon, so that a decorativey stripe is formed in the exposed surface of the welt extending parallel with theedge thereof in spaced relation from the bead. It will be seen that the tubeencased cores are thus connected to the backing 24 adjacent to but inwardly of its edges, this arrangement giving heavier and stronger edge portions to the welt and serving to more substantially secure the tube-encased cores thereto and to hold them firmly in resilient contact with the backing. It will furthermore be understood that each woven tube surrounds its core 17 and has both its sides or ends extending integrally over and secured to an edge portion of the backing in a manner providing multiple ply edges for the welt.

I have illustrated and described a preferred construction of woven i'iishin welt which presents the advantages above iscussed and which is suitable for finishing automobile upholstery and for various other purposes. It will be understood, however, that the invention is in no sense limited to the illustrated form of welting nor to the specific design of the weave. Where it may be desired to use the welt under different conditions from those mentioned, its proportions may be correspondingl varied and in some cases a greater number o beads provided on its face.

It will be apparent from the foregoing disclosure that I have produced a finishing welt of a type nOt heretofore available and which, by reason of' its characteristic integrally- Vwoven construction, is more durable and less liable to deterioration than welts fabricated from sheet material by the use of cement, stitching or other means. Its advantages from the stand oint of ornamental appearance have also een touched upon, it being possible to produce many variations of design both in the patterns of the weave and the color and character ofthe materials employed. It is, moreover, of special commercial value in that it may be conveniently woven of thread matching or blending with the fabric of the upholstery upon which it is displayed.

My invention not only provides a welt of greater uniformity and durability and one more attractive and ornamental in appearance, but in addition supplies a new article of commerce which can be produced mechanically at one operation to greatly cconomize in its cost of manufacture. `While I have dcscribed the improved welt as being woven, for example on a narrow ware loom, it is likewise capable of being' fabricated as a unitary structure on a braider `or other simi weft threads 16, in a position laterally of the y core or cores to form the backin strip.

It iste be understood, therefore, that I do meente not intend to be limited to the precise form or structure of the welt as herein shown and described, or to the exact method of fabrieating the same as disclosed, the improved article being .susceptible ot various modificationsi which would fall within the spirit and scope of the invention as expressed inthe appended claims.

My invention also includes within its scope a method of weaving the novel welt herein disclosed and which is characterized bythe steps of surrounding the bead cores with warp threads, providing a connecting row of warp threads and then weaving weft threads continuously about all the warp threads to form circularly-woven tubes upon the bead cores and a flat connecting portion.

Having thus described my invention', what I claim as new and desire to secure by Letters Patent is: Y
